Up until now, I just cant decide whether the ending was good, bad, or null.
But one that Im sure is that I DONT Like it.
Why bother to build up such storyline and characters on part 1 just to kill them off in such an out of context (from the story) way? just for a shake of darker story? well, guess what, its not! its a LAZY WRITING!
It just doesnt make sense how they turn young soo to a great villain of all Kdrama history in a blink of an eye. If they want to do that, do it in the right way with a proper build up story.
